The Hologram is slightly enigmatic. Characteristics often commented on are a strange sense of humour, a fondness for contrived situations and tricks, but simultaneously a concern that everyone's enjoying themself.
In appearance he tends to enjoy flickering in and out of visibility, with or without a heavy cowled Mage robe which hides his face. When others arrive at gatherings where he is present, he will often dematerialize from his current location and fade in by the newcomer to offer them a hard-light JellyBaby. (All the taste, and no sugar!)
The Hologram approves (in theory) of conspiracies, and of rules innovations like /TheProphecies which develop the World and add interest or possibilities to it.
